I agree with CJR... Sulmet is nasty stuff. Antibiotics are not that useful when you don't have a confirmed diagnosis....and wth our Faverolle..it would not have done much good as her illness would not have been determined in time. Our hens are like members of our family, so it's heart breaking when there is nothing you can do but try and comfort the bird. You might find a knowledgeable person at the grain store, we have southern states here and often you can find people that can offer suggestions. Good luck.
